A domain name is like an address for a website. It is a unique name that identifies a website on the Internet. Every domain name is registered to a specific owner or organization, and no two domain names can be the same. When someone types a domain name into a web browser, a request is sent to a global network of servers that form the Domain Name System (DNS). This system translates the domain name into an IP address, which is a unique numerical identifier assigned to every device connected to the internet. The IP address is used to locate the website and connect the user to its server, allowing them to access the website. Without a domain name, websites would only be accessible by entering their IP address, which can be difficult to remember and would require a complex system to manage.
